Matchbox is awesome! It is our first time to try dorm type capsule inspired room!
Staff are friendly and nice except for one. We arrived earlier than check-in time but we were welcomed and allowed to leave our bags on the 1st floor and stay in the common area at 5th floor while waiting. Common area is very vibrant and cool! It is airconditioned, has TV, free water, coffee and tea, a refrigerator, desktop with internet, and big beanies!
Booked the box for two and it was big enough for a very comfortable sleep even though all our bags were stacked inside. It has TV, a small safe box and a locket located on the base of lower boxes. Lockers are cabinets with of course, locks but base is the floor itself so make sure to elevate or put something under your gadgets (like laptops and tablets) because if someone accidentally spills any liquid, it will surely get wet.
Laundry and dryers are available at the common area and are operated by coins. We actually used it, 50 baht coins for the washing machine, 30 baht coins for the dryer and 10 baht for a small pouch of detergent.
Location is very good. Phrom Phong (BTS station of Sukhumvit line) is just 10 to 15 mins walk. You may not be at the center of everything but you have the fastest access to almost everywhere. Good street foods, restaurants, cheap buffets, convenience stores, thai massage spas, japanese inspired snack bars are just outside the building!
Definitely worth a try and an option when in Bangkok!
